Original Abstract Submitted

some embodiments of the present application provide for grouping of user equipment (ues) in clusters and/or tiers. the grouping may be based on a dynamically updated mean squared error-position/relative position map maintained at a transmission point. additionally, grouping may be implemented in a hierarchical and cooperative manner, such that some ues act, in a higher tier, as an anchor ue to other ues in lower tiers. furthermore, the ues may be understood to self-organize into clusters of ues. a cluster of ues may be represented by a single, representative ue to reduce signaling overhead between ues in a given ue cluster and various anchor ues and/or transmission points. moreover, cooperation between ues in the same cluster may be based on sensing and on sharing, among the ues, a relative position estimate and an position estimation mse associated with the relative position estimate.
